 (ûrth′kwāk′)
n.
A sudden movement of the earth's crust caused by the release of stress accumulated along geologic faults or by volcanic activity. Also called seism, temblor.

earthquake

(ˈɜːθˌkweɪk)
n
(Geological Science) a sudden release of energy in the earth's crust or upper mantle, usually caused by movement along a fault plane or by volcanic activity and resulting in the generation of seismic waves which can be destructive.

earth•quake

(ˈɜrθˌkweɪk)

n.
1. a series of vibrations induced in the earth's crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating.
2. something that is severely disruptive; upheaval.

earth·quake

(ûrth′kwāk′)
A sudden movement of the Earth's crust. Earthquakes are caused by the release of built-up stress within rocks along geologic faults or by the movement of magma in volcanic areas. They are usually followed by aftershocks. See Note at fault.
Did You Know? If all the dishes fall out of your cabinet, you may honestly be able to say, "It's the Earth's fault!" Indeed, the Earth has faults, cracks where sections of its outer shell (the lithosphere) slip past each other, causing an earthquake when subjected to great forces. Three kinds of waves accompany earthquakes. Primary (P) waves have a push-pull type of vibration. Secondary (S) waves have a side-to-side type of vibration. Both P and S waves travel deep into the Earth, reflecting off the surfaces of its various layers. S waves cannot travel through the liquid outer core. By contrast, surface (L) waves—a third type of wave, named after the 19th-century British mathematician A.E.H. Love—travel along the Earth's surface and do most of the damage associated with an earthquake. The total amount of energy released by an earthquake is measured on the Richter scale. On this scale, each increase by 1 corresponds to a tenfold increase in earthquake strength. Thus an earthquake measuring 5.0 on the Richter scale is 10 times stronger than one measuring 4.0. Earthquakes above 7 on the Richter scale are severe. The famous earthquake that flattened San Francisco in 1906 measured 7.8.

earthquake
